Bücher von Alex Lemon

His freshman year of college, Alex Lemon was supposed to be the star catcher on the Macalester College baseball team. He was the boy getting every girl, the hard-partying kid everyone called Happy. In the spring of 1997, he had his first stroke. For two years Lemon coped with his deteriorating health by sinking deeper into alcohol and drug abuse. His charming and carefree exterior masked his self-destructive and sometimes cruel behavior as he endured two more brain bleeds and a crippling depression. After undergoing brain surgery, he is nursed back to health by his free-spirited artist mother, who once again teaches him to stand on his own. Alive with unexpected humor and sensuality, Happy is a hypnotic self-portrait of a young man confronting the wreckage of his own body; it is also the deeply moving story of a mother’s redemptive and healing powers. Alex Lemon’s Technicolor sentences pop and sing as he writes about survival—of the body and of the human spirit.

Reviews the theory of low-rank semidefinite programming, presenting theorems that guarantee the existence of a low-rank solution, heuristics for computing low-rank solutions, and algorithms for finding low-rank approximate solutions. The book then presents applications of the theory to trust-region problems and signal processing.
